Just bad theme, a lot of function doesn't work as described.
Bad support, it takes A LOT of time to reply, and 90% of times not help...
The support guy says: sorry our develeper are too busy right now, wait a bit...
The support license ended and i'm still waiting...
STAY AWAY from this.
Buy better theme.
Have a better life.
